Langmuir films and Langmuir-Blodgett multilayers incorporating mechanically-threaded molecules-pseudorotaxanes

1996

This paper describes the synthesis of a π-electron rich aromatic lipid containing a polyether thread intercepted by a 1,5-dioxynaphthalene moiety. The terminus of one end of the polyether is a methoxyl group and the other a glycerol unit linked via the 2-oxo position, while the 1,3-oxo functions are covalently attached to octadecyl chains. This compound, when cospread at the air-water interface with the tetracationic cyclophane, cyclobis(paraquat-p-phenylene), and the phospholipid, dimyristoylphosphatidic acid, as its monoanion, forms self-assembled pseudorotaxanes which are self-organized into a two-dimensional supramolecular array at the interface. The electrostatic interactions between t…

Synthesis and cation-exchange properties of a bis-zwitterionic lamellar hybrid material

2008

The synthesis of a bis-zwitterionic lamellar hybrid material containing ammonium carboxylate groups is described. Cation-exchange properties of this material towards transition metal and lanthanide ions were studied as well as the regeneration and reuse of the material.

Fossili e contraddizioni dell’èra costantiniana: i dignitari del culto imperiale nella Tarda Antichità e il loro ruolo nelle “riforme religiose” di M…

2016

The imperial cult in Late Antiquity (4th-6th cent. AD) can be interpreted as a significant juridical fossile, which conveys the inner contradictions of the so called “era of Constantine”. An epigraphic and prosopographic analysis of the high priests of the imperial cult (flamines, sacerdotes and coronati in the West, ἀρχιερεῖς in the East) would point out the lasting importance of these dignitaries between the ages of Diocletian and Justinian, especially in the case of provincial high priests, who were in the same time presidents of federal assemblies (concilia, κοινά) and played a primary role in the “religious reforms” planned by Maximinus Daia and Julian the Apostate.

A new small mammal assemblage from the M013 Terre Rosse fissure filling (Gargano, South-Eastern Italy)

2013

Abstract The taxonomic study of the small mammal assemblage from fissure M013, sampled by a team of the University of Torino during the 2005–2009 excavations in the Dell’Erba Quarry (Apricena, Foggia) is presented. The assemblage includes the Echinosoricinae Apulogalerix cf. pusillus and the Crocidosoricinae ?Lartetium cf. dehmi; the Myomiminae species Stertomys simplex and Stertomys lyrifer; a new genus and species of Cricetodontinae and a single specimen of Hattomys cf. nazarii. Muridae include Mikrotia cf. parva, Mikrotia sp. 1 and a new genus and species of Murinae, phylogenetically related to Mikrotia. The occurrence of the new Murinae, the new Cricetodontinae, the two species of gliri…

Self-assembly scenarios of block copolymer stars

2011

We examine the self-organization scenarios of star-shaped AB-block copolymers, consisting of a solvophilic A-block and a solvophobic B-block, in which f such blocks are chemically anchored on a common centre on their A-parts, leaving the B-blocks exposed on their exterior. We employ a lattice model and we perform Grand Canonical Monte Carlo simulations for the case f = 6, varying thereby the percentage of attractive monomers as well as the concentration of stars. In agreement with previous studies on the low-functionality case f = 3 [F. Lo Verso, A.Z. Panagiotopoulos, and C.N. Likos, Phys. Rev. E 79, 010401(R) (2009)], we find that when the majority of monomers in the star are attractive, m…

Relationship between Prosocial Behaviours and Addiction Problems: A Systematic Review.

2022

The relationship of addiction problems with other pathologies or with different problematic factors has often been studied by psychology. Positive psychology is also currently approaching to these problems and their relationship with positive factors, such as prosocial behaviours. The purpose of this research is to carry out a systematic review of the scientific literature that has studied this relationship from 1900 to 2020. After the screening process with the inclusion and exclusion criteria, a total of 15 articles were selected. The main characteristics found in this relationship and the problems or limitations of investigations that have found relationships other than the mainstream, w…

Guided hierarchical co-assembly of soft patchy nanoparticles.

2013

Different polymers can be used in combination to produce coexisting nanoparticles of different symmetry and tailored to co-assemble into well-ordered binary and ternary hierarchical structures. There is considerable practical interest in developing the tools to fabricate multicomponent artificial systems that mimic the hierarchical ordering seen in the natural world — complex biomaterials can be assembled from the simple but precisely defined molecular building blocks. Andre Groschel and colleagues have developed a bottom-up approach that's a step in that direction. Previously they designed simple linear polymers that self-assemble in solution to produce monodisperse nanoparticles with well…

La ilustración de las "Empresas morales" de Juan de Borja: Erasmo Hornick

1992

LAS EMPRESAS MORALES DE JUAN DE BORJA, PUBLICADAS EN PRAGA EN 1581, OCUPAN UN IMPORTANTE LUGAR EN LA HISTORIA DE LA EMBLEMATICA Y DE LAS RELACIONES CULTURALES ENTRE ESPAÑA Y BOHEMIA. ESTE ES EL PRIMER LIBRO DE EMBLEMAS ESCRITO EN ESPAÑA Y, AL MISMO TIEMPO, EL PRIMERO EDITADO EN LOS PAISES BOHEMIOS. ESCASA ATENCION, SIN EMBARGO, SE HA DEDICADO A LOS EMBLEMAS QUE FORMAN LA PARTE GRAFICA DEL MISMO. ALREDEDOR DE UN TERCIO DE LOS GRABADOS SE IDENTIFICAN CON EL MONAGRAMA EH, QUE PARECE CORRESPONDER AL ORFEBRE, GRABADOR Y DIBUJANTE ERASMO HORNICK (AMBERES HACIA 1520-PRAGA 1583). EL ARTISTA MARCHO A TIERRAS ALEMANAS, DONDE ALCANZO GRAN FAMA Y RECONOCIMIENTO, Y DESDE DONDE MANTUVO CONTACTOS CON LA C…
